Test your choice! Use the model and control panel above to test your answer yourself:
  1. Click Run to see all three small molecules compete. Did you predict the correct partner?
  2. Stop the model and use the buttons to rotate/drag a small molecule into the binding site (Hint). Then click Run again to see if the potential partner is a good enough fit to remain in the binding site.
  3. Test one molecule at a time using the buttons in the panel next to the model.
